I heard about Steemit from a crypto group on Facebook in spring 2016. I was sent a blurb about some guy earning $1500 for one post along with a link to check it out. Took one look at the main page, saw the high-dollar trending posts and said "riiight" and clicked away.
But I came back a few days later, and kept lurking (and learning about Steemit) until I joined the following year. Those were the days! :)
